A memory device comprises an active area comprising a source and at least two drains defining a first axis. At least two substantially parallel word lines are defined by a first pitch, with one word line located between each drain and the source. Digit lines are defined by a second pitch, one of the digit lines being coupled to the source and forming a second axis. The active areas of the memory array are tilted at 45° to the grid defined by the word lines and digit lines. The word line pitch is about 1.5F, while the digit line pitch is about 3F.
